> The i40e driver complains about unprivileged VFs trying to configure
> promiscuous mode each time a VF reset occurs. This isn't the fault of the
> poor VF driver - the PF driver itself is making the request.
> 
> To fix this, skip the privilege check if the request is to disable all promiscuous
> activity. This gets rid of the bogus message, but doesn't affect privilege
> checks, since we really only care if the unprivileged VF is trying to enable
> promiscuous mode.
> 
> Testing Hints (required if no HSD): watch dmesg log while VF resets occur.
> You can trigger a VFR by unloading i40evf or shutting down the VM with an
> assigned VF.
